select the same vertices on view port and UV editor without selection sync? - python
BMLoop.vert



When iterating through the face loops (, which in case below is f.loops), the vertex of each loop element (l), is the vert property BMLoop.vert   of the loop. (l.vert). 

    for l in f.loops:        
        luv = l[uv_layer]
        if l.vert.select:
            print(luv.uv)
